The scientific consensus is that 5G is not dangerous to human health. The safety of 5G networks has been extensively studied and tested by experts in the field of radiation safety, and there is currently no credible evidence to suggest that 5G technology poses any significant risk to human health. The radiofrequency (RF) energy used by 5G networks is a form of non-ionizing radiation, which means that it does not have enough energy to break apart molecules or cause cellular damage like ionizing radiation, such as X-rays or gamma rays. In addition, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has established guidelines for safe exposure to RF energy, including… Read More

2.4GHz, 5GHz, and 6GHz Wi-Fi are different frequency bands used in wireless networks. 2.4GHz Wi-Fi is the older and more commonly used band. It is also known as the “legacy” band. It has a longer range and can penetrate walls and other obstacles better than 5GHz. However, it is also more crowded as many other wireless devices, such as cordless phones, Bluetooth devices, and even microwave ovens use the same frequency band. This can cause interference and slow down the connection speed. 5GHz Wi-Fi is a newer band and is less crowded than the 2.4GHz band. It provides faster data rates, but with shorter range and poorer penetration through walls… Read More

GPS, GLONASS, and Galileo are all global navigation satellite systems (GNSS) that provide location and time information to users around the world. Here is some information about each system: GPS The Global Positioning System (GPS) is a satellite-based navigation system developed by the United States Department of Defense. It consists of a constellation of about 30 satellites that orbit the Earth in a precise pattern, providing location and time information to GPS receivers. GPS is widely used in a variety of applications, including aviation, maritime navigation, and land-based navigation. GPS uses two carrier frequencies, L1 and L2, for transmitting its signals. The L1 carrier frequency has a wavelength of about… Read More

The IP “Ingress Protection” categories, also known as International Protection Marking, are used to specify the degree of protection provided by an enclosure or device against the intrusion of foreign objects, such as dust and water. The IP code consists of two digits, where the first digit indicates the level of protection against solid objects, and the second digit indicates the level of protection against liquids. Here is a summary of the IP categories: First digit: Second digit: It’s important to note that the IP code only measures the level of protection against dust and water and does not provide information on other environmental factors that may affect the performance… Read More

LoRa, or Long Range, is a wireless communication technology that is designed to enable long-range, low-power communication between devices. LoRa is a type of Low Power Wide Area Network (LPWAN) technology that operates in unlicensed radio frequency (RF) bands, making it accessible for anyone to use without the need for a license. LoRa uses a modulation technique called Chirp Spread Spectrum (CSS), which enables long-range communication while consuming very little power. CSS is a form of frequency modulation in which the frequency of the carrier wave varies over time, creating a “chirp” waveform. This chirp waveform is designed to be able to travel long distances without losing much signal strength.… Read More

LMR195 and RG58 are both coaxial cables commonly used in RF applications, but there are some differences between them that may affect their suitability for specific applications. Here are some key differences between LMR195 and RG58: Overall, LMR195 is a better choice for applications that require low attenuation, high power handling, and long cable runs, while RG58 is a more cost-effective choice for applications that require flexibility and moderate performance.

5G and 4G are two different cellular network technologies that are used for mobile communications, with 5G being the latest and most advanced version. Here are some key differences between the two: Overall, 5G is a significant upgrade over 4G in terms of speed, latency, and capacity, but its coverage is still being rolled out and its compatibility with older devices is limited.

SMA and RP-SMA connectors are very similar and often cause confusion. SMA stands for ‘SubMiniature Version A’ and is an RF connector used on high frequency systems. It is considered to be a robust connection due to the thread coupling and the excellent grounding provided. The RP stands for ‘Reverse Polarity’, meaning that the centre pin is moved to the female connector. SMA and RP-SMA connectors are not compatible for use together, they will either not couple or leave an air gap, depending on which combination is used. RP-SMA connectors are typically used for Wi-Fi antennas and some LoRa antennas. Whereas, SMA connectors are normally used for most other RF… Read More

We strongly discourage the use of splitter cables to overcome the need for dual / quad input routers, they will have a detrimental effect on the performance, as the power going in to each receiver is halved. This means that the distance that the signal can reach is reduced and the data throughput is reduce.

When an antenna has multiple 4G/5G ports, each port connects to a receiver on the internal radio, each receiver on the router is expecting a separate, independent signal.Using a single antenna on a dual input device will still operate fine, however to get the maximum speed, two single input or one dual input antenna is needed.Note: Dual input antennas use 2 separate antenna elements, they are not a signal antenna split across two cables.
